App that reads your mood and fights cravings put to the test
NCT ID NCT03538652
First seen Jun 26, 2026 · Last updated Jun 26, 2026 · Updated 1 time
Summary
This study tested a smartphone app designed to help people with opioid addiction by sending helpful messages at just the right moment. Nine adults who used heroin or other opioids carried a phone that beeped four times a day to ask about their mood and activities, then showed a message based on their answers. The goal was to see whether different types of messages (like problem-solving or mindfulness) worked better in different situations. The study was terminated early, so the findings are limited.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
smartphone app with cognitive-behavioral therapy (CBT) and acceptance and commitment therapy (ACT) messages
What this could lead to
If successful, this could point toward more effective, personalized smartphone tools to help people manage cravings and moods during addiction recovery.
What could go wrong
This was a very small, early-stage study that was terminated early, so results are limited. The app's effectiveness remains unproven, and it may not work for everyone.
